Very cool use of Workflows. Paired with dictation it’s an excellent on the go solution.
I modified @edgarasben’s workflow to add current date time and line breaks which is working well.
The UX is a bit confusing but if you tap on “Provided Input” a select menu opens but you can tap on the little keyboard on the left of the screen. That allows you to modify what you’re appending. CurrentDate is a default variable with a specifiable format. You can insert it there. I also create a LineBreak variable to insert two before the entry and one after the currentdate.
